A method for inhibiting tumor cell migration or metastasis of a cancer in a mammalian subject comprises one or more of the steps of administering to a subject a therapeutically effective amount of a composition comprising a molecule that: suppresses focal adhesion kinase (FAK) activity or phosphorylation suppresses ULK1 kinase activity suppresses activation or signaling of the mTORC1 (Ser757) pathway activates AMPK activates FIP200 or activates LKB1, in a cancer cell. Still another method of inhibiting tumor cell migration involves inhibiting phosphorylation of ULK1 on Ser757 in subjects with lung cancer. Suppressing activation or signaling of the mTORC1 (Ser757) pathway in subjects is in one aspect useful in treating lung cancer.
